Sergieiev // Shutterstock As frequent flyers know, air travel isn’t cheap. With the summer months in full swing, demand for air travel is expected to reach record numbers in 2024 as airlines continue to recover after the COVID-19 pandemic. Luckily for those who are looking for ways to save on travel, one way to cut costs on your next vacation may be in finding the right places to fly in and out of.  FinanceBuzz looked at average domestic airfares from the 45 busiest airports in the U.S. to learn which airports are best for travelers on a budget, as well as which ones to avoid if you are trying to travel affordably. Overall, the national average airfare cost decreased by 3.1% from 2022 to 2023 when adjusted for inflation (which translates to a 0.9% increase in non-adjusted dollars). The last time inflation-adjusted airfare costs dropped year-over-year was during the start of the COVID-19 pandemic, when it fell 18% between 2019 and 2020.   Largely, this is good news for consumers who can spend less on airfare and have more room in their budget for hotels, restaurants, and other travel fees. In addition to earning rewards on airfare, most travel credit cards offer rewards for spending in these areas, which can offset overall vacation costs. 25-year look at U.S. airfare costs FinanceBuzz Based on Bureau of Transportation Statistics, the above chart shows inflation-adjusted average airline fares over the past 25 years.  The least and most expensive airports to fly from For this report, we compared domestic airfares from the 45 busiest airports in the U.S. using data published by the U.S. Department of Transportation. Least expensive airports FinanceBuzz Orlando International Airport (MCO) had the lowest airfare cost in the country at $265.58 on average.  Home to iconic theme parks like Universal Studios, Sea World, and most notably, Walt Disney World, Orlando is one of America’s top tourist destinations.  This is welcome news for those bracing for expensive park tickets and food prices at the House of Mouse. Beyond saving with a Disney credit card on park-related purchases, visitors can also maximize savings by using a credit card like the Chase Sapphire Reserve which offers an annual travel credit, or even using a 0% APR credit card if you don’t want to pay for your entire vacation at once.  Another Florida-based airport, Fort Lauderdale-Hollywood International Airport (FLL), has the second-lowest average airfare cost in the country — tickets here are only about $5 more expensive than Orlando’s.  Just a few dollars behind FLL is Las Vegas’s Harry Reid International (LAS), where fares cost $272.15 on average. LAS is also the last airport on our list where average airfare costs are less than $300.  Oakland International Airport (OAK) has the fourth-lowest average airfare costs in the country at $303.79.

Save money on baggage fees by understanding your airlines and prepping for the hidden costs of air travel.  Methodology We looked at 2023 airfare data released by the U.S. Department of Transportation in May 2024 to compare domestic airfares by origin city. This report calculated average fares based on domestic itinerary fares. “Itinerary fares” consist of round-trip fares, unless only a one-way ticket was purchased. In that case, the one-way fare was used. Fares are based on total ticket value, including the price charged by the airline plus any additional taxes and fees levied at the time of purchase. Fares include only the price paid at booking and do not include fees for optional services like baggage fees. Averages also do not include frequent-flyer or “zero fares” or a few abnormally high reported fares. This story was produced by FinanceBuzz and reviewed and distributed by Stacker Media.
